What Causes Swollen Canned Food?

The concept of swollen canned food is a mystery to some and a bother to many. Canned food can swell for a variety of reasons, but the most common cause is microbial contamination.

When bacteria, yeasts, or molds enter the can, they begin to grow and multiply, resulting in an increase in the volume of the food inside the can. This is what causes it to swell.

Microbial contamination can occur when a can is not properly processed or sealed during production. If there are any holes or cracks in the can before it is sealed, then bacteria and other microorganisms can enter and begin to grow. This could also happen if there are any defects in the manufacturing process which allows air and moisture into the can.

Another common cause of swollen canned food is enzymatic activity. Enzymes are proteins that catalyze chemical reactions in living organisms. When fruits or vegetables are canned, some enzymes may remain active even after processing, resulting in enzymatic activity within the can which causes swelling.

Finally, swollen canned food could be caused by improper storage conditions. If a canned food item isn’t stored at proper temperatures or humidity levels, then this could cause bacteria or fungi to grow inside the cans and result in swelling.

Conclusion:

In conclusion, swollen canned food is typically caused by microbial contamination, enzymatic activity or improper storage conditions. It’s important to ensure that cans are properly processed and sealed during production as well as stored at proper temperatures and humidity levels to prevent this from occurring.
